"there's everything to play for ...

... And forever to play it in!"

The idea that the snooker commentators are probably drinking is very Britain, and especially Britain from a particular era.

I think that series came out slightly after that era ended, I remember as a child (so years earlier) realising that snooker players at the time were often tipsy if not actually drunk, and also darts players, but by the time I was an adult the professionalism really changed that, turns out that if you're very good you probably are better at snooker when sober. I think the commentators, being often a previous generation of players, lagged that slightly.
